vSPECIlICA'lION' forming part*v of Letters `:Patent No. 273,326, datedMarch 6, 1883.

Application led January 4, 1883.

To all whom it may concern:

Be it known that I, JOHN H. WARD, of Lowell,in the county of Middlesex,State of Massachusetts, haveinvented acertain new and useful Improvementin Car-Couplers,of which the following is a description sufciently full,clear, and exact to enable any person skilled in the art or science towhich said invention appertains to make and usethe saine, referencebeing had to theaeeompanying drawings, forming a part of thisspecification, in which- Figure l is a side elevation; Fig. 2, averticallongitudinal section, and Figz a top plan view.

Likeletters of reference indicate correspondingpartsin thedii'erentigures ofthe drawings.

My invention relates more especially to that class of car-couplers whichare automatic or seltcoupling in their operation vand it consists in anovel construction and arrangement.

of the parts,as hereinafter more fully set forth and claimed,by which acheaper, simpler, and more effective device of this character is produced than is now in ordinary' use.

rlhe nature and operation of the improvement will be readily understoodby all conversant with such matters from the following description, itsextreme simplicity rendering an elaborate explanation unnecessary.

In the drawings, A A represent the drawbars, and B the link. Thedraw-bar heads are each provided. with a longitudinal chamber, O, havinga flaring mouth, m. The rear portion., d, of each of the chambers opensthrough .the under side of the draw-bar head, and journaled therein onthe shafts D are two cam-shaped levers, E, each provided with anoutwardlycurved upwardly-projecting arm, G, and at their lower ends withthe toothed segment f. The shafts extend horizontally through thedraw-bar heads, and are provided at their ou ter ends with thehand-wheels H, being tirmly attached to the levers E in the chamber U.

Disposed on each ofthe shafts D, on either side of the draw-bar head,there is a ixed curved lever, J, and coiled spring K, one end of thespring being secured tothe shalt and the other to a laterally-projectingpin, L,which pin is also elongated and acts as a stop l'or the (Nomodel.)

draw-bar heads, as shown by the dotted lines in Fig. 3.

In the use of my improvement, one of the draw-bar headsbeing rstprovided with a link, B, if the cars are brought together, the free orouter end of the link will enter the cham- .ber C in the oppositeorcornpanion head, strike the curved or outer face of the arm G, forcingit back, and, passing downwardly, hook over the pin L in the throat ofthe draw-bar head, thereby coupling the ears in a manner which will bereadily obvious without a more explicit description. The springs K areso arranged as to force the arms G of the levers E against the hooks Zof the link B, therebyl keeping the hooks engaged with the pins L afterthe cars are coupled, or preventing the ears from being accidentallyuncoupled, the arms being curved and extending over the hooks,as seen inFig. 2.

Attached to the outer end of each of the levers'J there is a chain, M,extending to the platform or top of the car, and by pulling these chainsthe arms G will be forced away from the hooks l, and at the same timethe teethf on the levers E will be caused to engage the teeth u on thehooks l, thereby disengaging the hooks from the pins L, raising the linkB, and unconpling the ears. v'lhe ears may also be uncoupled insubstantially the same manner by turning the `wheels H, if preferred ormore convenient. i

It will be obvious that the pins L perform a triple service, acting asstops for the levers J, studs for attaching the springs K, and staplesfor the hooks Z, and when worn by the action ofthe hooks may be readilyremoved and new pins inserted.

The throat of the draw-bar head is so formed ati as to re-enforce orstrengthen the pin,

which in turn prevents the wear of the throat by the action ofthe hooks.

Having thus explained my invention, what I claim is 1. The improvedcar-coupler described, the

same consisting or" the link B, provided with the serrated hooks l, thedrawbar heads A, provided with the chambers G d and pins L, the leversE, provided with arms Gand teeth 5 f. and the shafts D, provided iviththe levers J, springs K, and Wheels H, construoted,com bined, andarranged to operate substantially as set forth.

2. In a oar-coupler substantially such as dero scribed, the pin L,arranged to serve as a staple for the hook i, a stop for the lever J,and a stud forthespring K,substant ially as specified.

3. In acum-coupler, substantially such as described, the link B,provided with thehooks Z, 15 in combination with the curvedyieldinglever G, adapted to receive the end-thrust of the link, turn itsfree end down into engagement vwith the pin L, and hold it in Contact.therewith, substantially as described.

4. In a car-coupler substantially such as described. the levers J,provided with the chains M, mounted on the shaft D, provided with thesprings K, substantially as set forth.

5. In a car-coupler substantially such as described, a link having.r twodownwardly-projeotinghooks for engaging the draw-bar heads, and providedwith serrations or means whereby they may be lifted out of engagementtherewith, substantially as specified.
